Uniform convergence of the Fleming-Viot process in a hard killing metastable case

Probability 2024-11-22 v3

Abstract

We study the long-time convergence of a Fleming-Viot process, in the case where the underlying process is a metastable diffusion killed when it reaches some level set. Through a coupling argument, we establish the long-time convergence of the Fleming-Viot process toward some stationary measure at an exponential rate independent of NN, the size of the system, as well as uniform in time propagation of chaos estimates.
